Abstract: Several different symbols may be assigned to each key of the keyboard as requested by the operator. All the various symbols of the keys are recorded in a memory where they are organized in a certain number of pre-defined, distinct configurations of the keyboard. The configuration chosen by the operator is recorded in a display memory and displayed by means of a graphic unit on a flat panel, for example a liquid crystal display panel. The key actuated by the operator is identified by a decoding circuit to determine its symbol by means of the display memory and to display it on the flat panel.

Abstract: An electronic labeling machine is disclosed which includes a printing mechanism with a carriage adapted for horizontal travel across assemblies of identification devices to be imprinted. A web sensor is attached to the carriage for concurrent travel therewith. In traversing horizontally across the assembly, the web sensor provides a signal to a microprocessor which indicates the presence or absence of the assembly under the current position of the sensor. The microprocessor also receives a timing signal from the printing mechanism indicative of the position of the carriage. Based on the timing signal and the signal from the web sensor, the microprocessor measures a current width of the assembly. The assembly is especially adapted for use with the invention, and includes notched portions having a width different than the nominal assembly width, each notched portion being in a fixed relative position with respect to one of the identification devices.

Abstract: The present electronic typewriter comprises a memory for storing English sentences inputted into the electronic typewriter by operating its keyboard, a dictionary memory, in which data on plural English words are stored, and a spelling check control system. The typewriter is also provided with a checking execution key for checking the spelling of each English word of the English sentences stored in the memory. When the checking execution key is operated, a English sentence data stored in the memory are read out by the spelling check control means which judges the coincidence with those stored in the dictionary memory. If it is judged by the spelling check control means that the English words of the English sentences stored in the memory include a word not corresponding to any of the English word data stored in the dictionary memory, the printed position of the word on the printing paper is determined by a printed position detection means on the basis of the English sentence data stored in memory.

Abstract: A synthetic resin pen unit has a cylindrical outer annular member with inwardly extending bent and straight members. Each bent member has a base portion extending from the inner wall so that it is inclined with respect to a phantom line connecting the base of the bent member to the central axis of the cylindrical member. Ink grooves are formed between the inwardly extending members. The flexibility of the pan unit is a function of the percentage of bent members so that by proper selection and arrangement the pen characteristics can be optimized.

Abstract: A thermal color printer includes a reversible platen roller 9 and associated pinch rollers 11, 10 on the paper feed and discharge sides. The paper is repeatedly advanced back and forth through the printing station to successively print the different color separations. The discharge side pinch roller 10 is coupled to the platen roller by "unequal" spur gear 31, 32 and one-way clutches 33 such that it is frictionally driven by the platen roller in the sheet advance direction and gear driven by and at a slower speed than the platen roller in the reverse or sheet return direction. This serves to tension the sheet of paper during each return conveyance to thus maintain it in tight contact and registration with the platen roller, thereby avoiding offsets between the successive color separation printings and attendant fringe patterns.

Abstract: Electronic word processing is carried out with a keyboard including character keys and attribute keys. Attribute codes input by the attribute keys are stored in an attribute code memory in accordance with the sequence of attribute key operation. An attribute pattern corresponding to an attribute code read out from the memory is read out from attribute pattern memories, and is printed by a printing section after compounding by an instruction from an attribute compounding designation section.

Abstract: A data entry system comprising a one-handed keyboard having five data keys and five control keys which are used in combinations for entering data and control characters in the system.

Abstract: The present invention is of a character-erasable printing apparatus adopting an erase controlling means which outputs to a printing mechanism a move control signal moving a printing head to the print position of the head character of a character string corresponding to the printing head and subsequently outputs to an erasing mechanism an erase control signal erasing characters sequentially from the head character to the last character on receiving an erase command from an inputting means.

Abstract: A form overlay type document printing apparatus includes a format memory for storing form data, a repetition data memory for storing common data to be printed on successive documents, and a variable data buffer for storing data which is unique to such document. A printing pattern generator converts the repetition data and unique data to corresponding printing signals and a form pattern generator generates printing signals for reproducing a selected form. The printing signals corresponding to the form data and the repetition data are combined and repetitively supplied to an output buffer as long as there is no change in the form or the repetition data. The printing signals corresponding to the unique data are also supplied to the output buffer. The contents of the output buffer are supplied to a head driver which controls a printing head to generate the desired printed output.

Abstract: A hand held thermal printer has a hingedly mounted bottom cover which can be opened to provide comfortable access into the printer and therefore substantially simplified loading of a roll of labels into the printer. The platen roller of the printer which normally abuts the print head of the printer is supported on a pivotable platen arm. The platen arm, like the bottom cover can be pivoted to an open position to provided direct access to the print head. The print head is held in place by a retainer plate which is held by screws and the screws can be simply loosened to permit the print head to be easily replaced. In the open position of the platen arm a wide and straight label passage is created through which the leading end of the backing sheet on which the labels are located could be easily threaded into the printer.

Abstract: A typewriter having a function of automatically indicating a candidate correct word for a misspelled word and, including a control device operable upon operation of a suitable key for checking entered words against data stored in a dictionary memory to find any wrong word; and if any wrong word has been found, for searching for at least one candidate correct word for the wrong word from the words stored in the dictionary memory; and for displaying the candidate correct word in relation to the wrong word. In place of, or in addition to the above function, the typewriter may have a function of automatically correcting a misspelled word, with the control device being operable upon operation of another suitable key, for activating erasing and printing mechanisms to erase at least wrong characters of the wrong word and print correct characters to correct the wrong word, according to the data representative of the wrong and correct words.
